introduction : the purpose of this study was to examine and compare the social adjustment in balanced and non-balanced patterns of the parent-child relationship.  methods : the research population was all female gifted students in the farzanegan high school in the first educational district of tehran in 2013-14. the sample research included 96 female gifted students who answered the parent-chil...

in this paper, we consider a cooperative cognitive radio network in which there is an ofdm primary link and multiple single carrier secondary links.the primary link is required to maintain its secrecy rate above a predefined threshold. if the secrecy rate requirement is not satisfied, the secondary system help primary link to maintain its secrecy rate requirement. in doing so, the secondary trans...

The role of multiple antennas for secure communication is investigated within the framework of Wyner’s wiretap channel. We characterize the secrecy capacity in terms of generalized eigenvalues when the sender and eavesdropper have multiple antennas, the intended receiver has a single antenna, and the channel matrices are fixed and known to all the terminals, and show that a beamforming strategy...

The Secure Digital Music Initiative is a consortium of parties interested in preventing piracy of digital music, and to this end they are developing architectures for content protection on untrusted platforms. SDMI recently held a challenge to test the strength of four watermarking technologies, and two other security technologies. No documentation explained the implementations of the technolog...

Existing microgrid communication relies on classical public key systems, which are vulnerable to attacks from quantum computers. This paper uses distribution (QKD) solve these quantum-era challenges. Specifically, this makes the following novel contributions: 1) it devises a QKD simulator capable of simulating protocols; 2) offers QKD-based architecture for microgrids; 3) shows how build quantu...
